[texts]VRA Modeling, phase 1 - Kindt, Louis M.
The destruction of organic contaminants in waste water for closed systems, such as that of Space Station, is crucial due to the need for recycling the waste water. A co-current upflow bubble column using oxygen as the gas phase oxidant and packed with catalyst particles consisting of a noble metal on an alumina substrate is being developed for this process. The objective of this study is to develop a plug-flow model that will predict the performance of this three phase reactor system in destroyi...

[movies]Merging Black Holes - NASA
A black hole is a massive object whose gravitational field is so intense that no light (electromagnetic radiation) can escape it. When two orbiting black holes merge, a massive amount of energy is released in the form of jets. Meanwhile, the movement of these massive bodies disturbs the fabric of space-time around them, sending ripples of gravitational waves radiating outward. These waves are predicted by Einstein's theory of general relativity, but have yet to be directly detected...

[movies]Millisecond Pulsar with Gravitational Waves - NASA
A pulsar is generally believed to be a rapidly rotating neutron star that emits pulses of radiation (such as x-rays and radio waves) at known regular intervals. A millisecond pulsar is one with a rotational period in the range of 1-10 milliseconds. As the pulsar picks up speed through accretion, it distorts due to subtle changes in the crust. Such slight distortion is enough to produce gravitational waves...

[texts]Job Scheduling in a Heterogeneous Grid Environment - Shan, Hong-Zhang
Computational grids have the potential for solving large-scale scientific problems using heterogeneous and geographically distributed resources. However, a number of major technical hurdles must be overcome before this potential can be realized. One problem that is critical to effective utilization of computational grids is the efficient scheduling of jobs. This work addresses this problem by describing and evaluating a grid scheduling architecture and three job migration algorithms...

[texts]FUSE Analysis of the Cyg OB1 Superbubble - Nichols, J.
FUSE observations of four stars in the line of sight to the Cyg OB1 IR-detected superbubble have been analyzed for high-velocity features in the O VI interstellar lines, which might be attributed to the shock structure of the superbubble. Multiple components were detected in the spectra of all four stars, with a velocity range of -85 kilometers per second to 29 kilometers per second. As many as four separate velocity components were identified in each spectrum, implying multiple shock structures...

[texts]Navier-Stokes simulation of transonic wing flow fields using a zonal grid approach - Chaderjian, Neal M
The transonic Navier-Stokes code was used to simulate flow fields about isolated wings for workshop wind-tunnel and free-air cases using the thin-layer Reynolds-averaged Navier-Stokes equations. An implicit finite-difference scheme based on a diagonal version of the Beam-Warming algorithm was used to integrate the governing equations. A zonal grid approach was used to allow efficient grid refinement near the wing surface...

[texts]Attenuation of upstream-generated low frequency noise by gas turbines - Doyle, V. L.
The acoustic transfer functions of low frequency (below 3500 Hz) noise through aircraft turbines were investigated. Model test results were compared with theoretical predictions in order to assess the validity of the theory. Component tests were conducted on both high pressure and low pressure model turbines. The influence of inlet temperature and turbine speed attenuation was evaluated, while the effects of turbine pressure ratio, blade-row choking, and additional downstream stages were determi...

[texts]A Glass Can Be Half Full: Even in Microgravity - Sutliff, Thoma
When conducting physical science research in space, the smallest vibration or disturbance can disrupt sensitive experiments. Back in the 1990s we developed an instrument, the Space Acceleration Measurement System (SAMS) that flew on the shuttle to monitor the vibration environment - but it wasn't very flexible. It could only measure vibrations for three users and only at fixed frequency ranges, and it had to be disassembled after each two-week mission to be readied for reuse...

Although there are many presentations of our current understanding of this subject on the market, the topics covered in the second chapter of the...
